[meta-openembedded][PATCH v3 1/3] e2fsprogs-ext4sparse-native: compiles ext2simg.c using android-tools-native

[AshishKumar Mishra <emailaddress.ashish@gmail.com>]

Add a custom do_compile step to build the  ext2simg_android utility (ext2simg)
when building for the native class.
This can be used to generate ext* based sparse image
